# Walmart Ad Engine Goes Off Platform as OpenAI Threatens to Eclipse Retail Media - Digital Ads & Retail Media Weekly - Week of July 19, 2026 > Digital-ads and retail-media podcast intelligence for the week of July 12 to 19, 2026. Walmart Connect now drives about a third of Walmart's operating income and is activating shopper data on Google's YouTube and DV360, Google's search revenue grew 19 percent heading into July 22 earnings, Fox bought Roku for $22 billion, and OpenAI's ad chief argued ChatGPT advertising could eclipse the $150 billion retail media market. ## Digital Ads & Retail Media Weekly ### Week of July 19, 2026: Walmart Ad Engine Goes Off Platform as OpenAI Threatens to Eclipse Retail Media --- ## TL;DR - **Walmart is done playing defense.** It folded its ad units into one pitch, put its shopper data onto YouTube through a Google partnership, and, per its own executives, Walmart Connect now makes up roughly **a third of the company's operating income**. Retail media is no longer a side hustle; it's the profit engine. - **"Search is dead" got quieter this week.** Two investing podcasts hammered the point that Google's **search revenue grew 19%** even as AI answers spread, and Alphabet reports earnings **July 22**, the number everyone in ads should watch. - **The scariest chart nobody drew:** OpenAI's own marketing chief says the ChatGPT ad platform, live for four months, could **eclipse the ~$150 billion retail media market**. If AI chat becomes where shopping decisions get made, every walled garden (Google, Meta, Amazon, Walmart) is defending a moat that just moved. --- ## What's new **1. Walmart turned its shopper data into an open-web weapon.** On [Ecommerce Braintrust](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOgWNd8BM7TUkneOxUBU2vEIG6zVYzOIyFNZPatA6-2BgJplb63w-2B97TdOQ0YHTn7s6UmYyKSbjgi9u3Ck83mUVpa3F92MJUI7QpqxBk6sErYgjw-3D-3D_ji1_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RLC5Orh5y6aIpxbXegaOQVqT-2F0rLLNi6atBcJG0JuDtHeA6GEkweclnu1NToVdfi9X8NSO-2Bqrn13y5z1kYvJ8eEJN3J-2Fy32BBnoM-2FaOBcLBNSlFyvpYpzDQ8YjPgDumj8w-3D-3D) (July 14), agency operators Jordan, Armin and Pat walked through Walmart's partnership with Google's DV360 and YouTube, which lets Walmart activate its first-party purchase data (the record of what you actually bought) on properties Walmart doesn't own. The clever part: YouTube is "one of the few places Amazon's ads can't go." A brand can now run an awareness video on YouTube and tie it directly to a sale inside a physical Walmart store. Why it matters: for most brands, Walmart's online sales are only 10–15% of their Amazon volume, so Walmart can't win a traffic war on its own website. Instead it's going out to meet shoppers where they already are and dragging them back to its 10,000-store base. **2. Walmart executives put a number on the ad engine, and it's huge.** On [The CPG Guys](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOg-2FJwEV5oYCZWc5blxmwLUJ19ygP2ZyRujoWpZhrDtvroeKpFtBWhaUM1Un-2F88ZD3T-2B-2FqBcmev7d7ayYj2kykNADZ6vQeLhwjzp0qkcIf9PDQ-3D-3Dgp3S_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7ROQqcxt8pdlFH10-2B6X1Eqo2erfXs0iCO3BKE2-2FlTR7ZqXSRk9lFmGrJ0pdXKrsQnZQcj89YEbgJHhkPSLwoFs6DF39ggw8sU-2B7p0fwFhwoO0nsnH-2BemP7MNcCe-2BPf5r-2B-2Bg-3D-3D) (July 15), Walmart+ leaders Sri Rajagopalan and Deepak Maini said Walmart Connect grew about **33% in the U.S. last quarter** and, together with membership fees, makes up **about a third of Walmart's operating income**. The fuel is membership: Walmart+ members shop 3x more often, with 7x more online visits and 2x more store visits than non-members. That's operator commentary, straight from the people running it, worth separating from the analyst chatter. **3. Google's search machine refuses to die.** On [Schwab Network](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOhUzhPz-2FlE-2FiiPsas8uLqXP7cWo3aChb6o1WpPL5psuuDjoXaN7cvHdOo9q-2FLCewlvAEgX-2BrwDNqhjvHGxxVz6EYwmQE2WdOvmggcQGShf8uA-3D-3DDNIm_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RMs-2BFeVXrZ11QzlSmOVl4xKETiY8ouXD9W17z3ptWUQXTo1M7fSm320pctyR352RrcgGOYHsCQ7JUQC44NROomg2JoN4U3WumnjAtsgI6wb-2BLuWn3OR7KujPcs5cCHFbvw-3D-3D) (July 16), analyst Jason Brown noted Alphabet's revenue rose 22% while **search revenue grew 19%**, a direct rebuttal to the "AI will replace search" bear case. His take: "It's not either/or, it's both/and." Why it matters: this is the single biggest debate in the sector, and Alphabet reports earnings **July 22**, the first real read on whether AI answers are eating the ad business or sitting alongside it. **4. Fox bought Roku for $22 billion, and ad targeting is the whole point.** On [Behind the Numbers](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOhU84HjjYcoJW9Ua8saP-2BoYu-2FWa8ZS7xlTfxhiymznKkVtbhmSeaMVnHxqcYoGbX1hxLqWwQavKjfiY4EOb82GwW6Knh0uUryrX9KGdAADVGw-3D-3DBpwo_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RIipQEFvbYPx4JyXJXuDUfo2Q8BCQktr0FKwrRwXPwLrssNen9HqPESWvJLRj99K6aqP4L2u3sMPGNP76ENze5-2FzIVsSgteMZFnRk84LGshIEIoya7mNF-2BrYFt27mTG2JQ-3D-3D) (July 13), the EMARKETER team (Marcus Johnson, Ross Benish, Ethan Cramer-Flood) explained that Fox is buying Roku for its 100 million-plus households and the hardware-level data from Roku's operating system: "targeting capabilities that rival Amazon and Google." Connected TV (CTV) simply means streaming you watch on a TV screen. Combine Roku's free ad-supported channel with Fox's Tubi and you get a 5.3% share of U.S. viewing, enough to jump past Disney into third place, behind YouTube (13.4%) and Netflix (7.8%). **5. OpenAI's ad boss thinks chat will swallow retail media.** On [Uncensored CMO](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOj-2BTkSP-2BVwcnwbuv4JfSwqOm3uM-2FKa60AIcTlUe3HU63KisnKABUQo-2B3foB63f63TILsnTfYsAbGaN6LY0MmsKVJ9rBqUuvzquBV-2F4L0Hi6fw-3D-3DchGN_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RF-2FeCA-2B9Z6023R-2FMUwWMu3-2F73yn-2BOqVMQZi3IZ-2F5QqZ35QUk6BmUssiHAzDHlobRHYGG-2BvpQtn9FQyeivadcAtJ3LxBxHgxw5wS0y7KA1EMeDP-2F6Pa9cMo6K-2BiZuIDPGhw-3D-3D) (July 13), OpenAI's international marketing lead Elke Karskens said the ChatGPT ads platform, launched in February, now live in seven countries with Brazil and Mexico next, already works with Dentsu, WPP and Omnicom, and has shifted from a CPM model (paying per thousand views) to a CPC auction (paying per click). BCG's Mark Abraham put the stakes bluntly: "Seven years ago we predicted retail media would be a $100 billion business, now it's $150 billion, you're going to see LLM advertising eclipse that, because that's where people are." That's the operator (OpenAI) and the consultant (BCG) both saying the pie is about to move. ## The debate **The bull case: AI and retail media are growing the pie and hardening the walls.** The evidence this week is real. Walmart is monetizing data it already had, at ~33% growth and a third of profit. Google is proving AI and search can grow together (+19%). Fox just paid $22 billion to get into targeted streaming ads. And OpenAI is opening an entirely new ad surface where shoppers arrive already knowing what they want. Every one of these players owns something rivals can't copy: Walmart's stores, Google's search and YouTube, Amazon's checkout, OpenAI's chat. Adam Soroca, former product chief at ad-tech company Magnite, framed it well on [AdTechGod Pod](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOgUfUZzfsBXmcGoCSKmXQTsTonaKoym1LeO-2FcJA27jNFGs9773Nwmf-2FdYPimXo2X8dXile-2FUVYT7IdyqdAr91-2B2z5fOr-2BF7VNaX0MHjllYaUw-3D-3DQGjJ_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RPK9HqtH-2B-2BDwm5mXvMJZMbfn7yav-2ByFyO6pghq9OFg0x6Elmx1v4Ko6-2Bj50Q71F72tNjCvpW3j7crWGeAKU3TrIzFrxTpo2ceHVqEITun3MtP43hy0UQ5F8ttcfYWfZ8qw-3D-3D) (July 14): the industry is shifting from commodity "pipes" to defensible "lanes" built on unique data. The giants each get a lane. **The bear case: AI search could hollow out the very moment retail media sells.** Retail media makes money by charging brands to be found while a shopper is deciding. But AI is collapsing that deciding step. On [Future Shop](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOintDG-2FK9lrY15BwqrCEgTy8HLoXfoKQLDrk60dBLUStTuJcHgU45xvD2FtY4g7V0jfYl2yBs21PY7iqVtKgbH2SeIbAyg1nX3pqNdwjRygIQ-3D-3DbO8W_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RJv71gjlFvbvaCDUqbEJjAswP8Pp-2Fge25kbJoAYsHHHV0a1dGjxeh9kjWH2VZZkarzPhnJBt3Y1dx0OHQSa-2B-2FvzSu-2FFphPDqbbqBjnGPdNVGtECcKJp34TTwbhuG9ShjaQ-3D-3D) (July 16), Kiri Masters of the Retail Media Breakfast Club described buying a hair tool by giving ChatGPT her criteria and letting it narrow thousands of options down to one, then just picking a retailer to buy it from. She cited Shopify data that ~55% of AI-referred shoppers land straight on a product page, versus ~20% from organic search. If the machine decides before the shopper ever sees a sponsored listing, the discovery inventory that funds this whole boom gets thinner. Add Soroca's caution that in agentic ad buying (AI systems buying ads on your behalf) "money is just not flowing through the pipes yet", the hype is way ahead of the dollars. **Where I land:** both are true at once. The incumbents are getting richer *and* the ground under them is shifting. The tell to watch isn't the growth rate, it's the take rate (how much of each ad dollar the platform keeps) and whether AI chat starts pulling real budget, not just demos. ## Stocks in play **Alphabet (GOOGL)** - *Bull:* Search grew 19% despite AI fears; on [Investing Unscripted](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOh002eSub7SfVD151nkhz1Nsnv2rf-2BeuHj3Ryd6BuiHBSPS0c-2BJf0y8DwsJFitqViD89TGCwUlFOeVTZneHgEBGQ-2FDbngeZ-2BAN3ZO6Kq-2FjD2Q-3D-3DAmMW_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RNha8Xp-2Fx-2BGqryFhtge92U6R8gdJC16Nz2Ki23HibPwlzPa3ls7rNLzDUjRy3ZqhkgqnQJXe35zwI7Ze-2BJkYpRXUPJJBUOtBiF87dQMsNvYMreHaOeKHu0VjTQpLwW-2BARA-3D-3D) (July 15), the hosts called the ad business "incredibly strong," said Alphabet has "the easiest path to monetizing" consumer AI, and noted it's up ~18% this year, the best of the Mag7. One host, a Gemini user, said he's "already starting to see how Gemini ties into their ad-facing business." - *Bear:* At ~28x trailing earnings, it's near its most expensive in five years (it was 16–17x as recently as early 2025). And there's a real conflict ahead: serving advertisers who want prominence versus subscribers paying $20–$200 a month who don't want to be sold to. - *Watch:* **July 22 earnings**, specifically the search revenue growth rate and any color on how ads show up inside Gemini. **Walmart (WMT)** - *Bull:* Retail media is ~a third of operating income and growing ~33% (U.S.); the Google/YouTube deal extends its reach off its own site; ad margins dwarf grocery margins. - *Bear:* On [The Watson Weekly](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOi9a2IspFY4U2JWUxVor6qA-2FpGzB6RCFtx0hKNFDY2gmsdvWR6kfKhznSVndzPXkJwKBXvmwbnqqrnLgVjKAElqbk2KLLiNDGIrGrzpev0rjg-3D-3Da-hi_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7ROmo-2FQBF8JBJGxx84ajiTvFqr8ZbiEjsomM4kkDOCaFymMLNgkWXgTZTAFlDKhVUP1ePaUYLcCbe2Y3C9ol2iLaxYq-2F-2FNgAbnH2eFQT5Ogd12ATUga8JclEA3N5BP2FVPg-3D-3D) (July 13), Rick Watson flagged the open question: will advertisers buy the bundled "one Walmart" pitch, or three separate businesses? And its Sparky AI agent depends on clean product catalogs, which many big brands don't have. - *Watch:* The **take rate** as retail media competition intensifies, and Sparky's move from app to open web. **Fox (FOXA) / Roku (ROKU)** - *Bull:* $22B buys Fox 100M households and Amazon/Google-grade targeting; it could dominate free ad-supported streaming with Tubi + Roku Channel. - *Bear:* Investors sent Fox shares down on the news; TD Cowen's Doug Kreutz noted the ugly history of content-platform mergers (AT&T/Time Warner). Roku's own ad growth was already slowing, part of why it sold. - *Watch:* Whether Fox keeps the two streaming platforms separate (as stated) or merges them, and early signs it can actually run an ad-tech business. **Amazon (AMZN)** - *Bull:* Per [Ecommerce Braintrust](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOgWNd8BM7TUkneOxUBU2vEIG6zVYzOIyFNZPatA6-2BgJplb63w-2B97TdOQ0YHTn7s6UmYyKSbjgi9u3Ck83mUVpa3F92MJUI7QpqxBk6sErYgjw-3D-3DeCld_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RDZ1WN3RLlXmcPafU2S-2BrbdnMfAMD5NL82Mur-2FVg0Pc41bqeDuSwL-2BRCO5OgSzhLg19XSvlCtlTUL5KeU5L-2BMa56IJe-2F7-2BHLKXqwLRls2GeJrApqfCOTeO7DNxYV8aNLJA-3D-3D), Amazon is pulling more advertisers in by making its measurement tools free: it removed the paywall on AMC first-party insights (free to query through year-end) and added a multi-touch attribution toggle right in the ad console. - *Bear:* By democratizing the tools, Amazon erodes the edge big brands used to pay for; and its ads still can't reach Google-owned YouTube, exactly where Walmart just planted a flag. - *Watch:* Whether "free tools" translates into higher ad adoption and spend from smaller sellers. ## Read-throughs - **Emerging platforms (RDDT, PINS, SNAP, APP):** A quiet week. Reddit got only a passing mention on [Strategy Talks](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOjHRl-2BXkQ78rxwnIvkOQUOuIt0Z70rCEWdIXh2Cd3mBKEWgeL8tZTaeAH1Iwy3Sg3GJ2Em9z4PVs3zT6nYL0WCfQqmiWDPH-2FO9J5OE1DF0H6w-3D-3D76Nk_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RM47hfj2ZZoOfEjWdZSEs4PPuWJAqc-2BNfHEF66YnB5zEd9tByzM7XB-2BeAzufTQc1C4cctkJegHjBczQ3Jrbe6xfUg93u0P1ZXkRTjbLVB3jAjI2Qwsk1v-2FDSV7zOt7jdRg-3D-3D) (July 16), Jonny Waite noted a newer "max campaign type" and ~3x ad growth in the past year, but no real analysis. **Pinterest and Snap had no dedicated ad-revenue coverage. AppLovin only appeared in sponsor ad-reads and passing e-commerce mentions**, not substantive discussion of its AXON ad engine. - **Retail-media operators (WMT, CART):** Walmart dominated (see above). Instacart appeared mainly as a sponsor and in passing retail-media context, without fresh financial detail this week. - **CTV / streaming:** Fox/Roku was the marquee story. Broader streaming chatter centered on free ad-supported tiers as the growth path. - **Ad-tech and measurement:** Criteo's Todd Parsons appeared on [The Agile Brand](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOieG9f-2FziKN5z1CGGO1u5DaEngtBx9eqvaavrQRZqinKIuc8lmGcZw9Vp-2F4p33xEd6Fkwc6kKKx0GJLfYlE0JZxr692-2BJRmtDU4azM2OXCLBQ-3D-3D_2Pv_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RPYcOvPN1V9sNVqcKujRNG4M-2FKwt9vjNdazLJ3QWomXg8rL3EmQ86IalC2P7YV1MbbmxiX44cm-2BFPJIwu0OirNQ4-2BYKAOfBALjI9y30ngbTwClgsXzoMfswezwxFYmVNtA-3D-3D) (July 16) pitching Criteo GO, a self-service tool that runs ads across display, web, video, social and even ChatGPT, always tuned to the client's own "source of truth" for measurement. On measurement more broadly, Acoustic CMO Alexi Hatch argued on [The Agile Brand](http://url7324.matterfact.com/ls/click?upn=u001.idHmPrr2Geh7KYLAsTy7NkrIVb-2FgA4pmf2rMXQwGcOg9bdmmxQYTbRYSqTVP3n9JgXIOxIW-2BPyVpzp-2BZG4ZMADGdKm35gGERZPsz5P3gdND1yrHR-2BDWzD7D27tVru8pi4wpfj2Ksz-2FM8c1APIy2-2FTg-3D-3DAlL3_7mLGwmUci-2BLaXswv9WX1yTgqn3Wad-2FotHhzHgSNAZbWZf934htAPWsZPvmWWYQpZhEVmMTW08HL3sUXwHtd7RHqOuOKDIVilr75xyQyOJxlK9NDeRH-2BVyYOmyU4WPMqL8L3bIRYGRv1x7RLIrl3Jp13wvyFUEn-2Bx4TeEXELwqOYtFZnAx8-2B-2BndDrECVqH1HWY9ANq8cZre-2FBgv16xRi4NA-3D-3D) (July 17) that privacy changes from Apple and Google have broken perfect attribution ("every problem is an attribution problem"), and marketers should act on 85% of the data now rather than chase a perfect model that no longer exists. - **Genuinely no coverage this week:** The Trade Desk (TTD): nothing on Kokai or UID2 despite a direct search. **DoubleVerify (DV), Integral Ad Science (IAS) and LiveRamp (RAMP) drew zero episodes.** The ad-verification and identity-infrastructure names simply weren't part of the conversation. ## What changed vs last week Busier than a typical mid-summer week, and the center of gravity shifted decisively toward **retail media going off-platform** (Walmart onto YouTube) and **AI chat as an ad surface** (OpenAI's "eclipse retail media" claim). The through-line from ad-tech veterans (Soroca on "lanes," Parsons on breaking channel silos, Hatch on the death of perfect attribution) is that the walled-garden-versus-open-web line is blurring fast. What stayed quiet: the independent ad-tech and measurement names (TTD, DV, IAS, LiveRamp) and the smaller social platforms (PINS, SNAP). If you cover those, this was a thin week, and the silence itself is worth noting. --- ## Get the full transcripts on Matterfact This briefing was produced with Matterfact, which indexes the complete, full-text transcripts of 120M+ podcast episodes alongside SEC filings, earnings calls, and financial datasets.
